Yes, herpes can still be contagious when it's in the form of a dry scab. Even though the virus is less active during this stage compared to when there are open sores or blisters, there is still a risk of transmission if contact occurs with the affected area. It's best to avoid skin-to-skin contact until the scab has completely healed and fallen off naturally to reduce the risk of spreading HSV (Herpes Simplex Virus) infection. Also, maintaining good hygiene practices like washing hands regularly can help prevent unintentional spread of herpes during outbreaks.
